古往今来，中外有着多少坚毅执着，勇于探险的人们啊，他们其间不是经历常人无法体验的激情与成功，就是经历常人难以想象的悲壮与失败…… From ancient times to modern times, there are many persistent and adventurous people at home and abroad. They experience either passion and success that ordinary people can't experience, or tragedy and failure that ordinary people can't imagine 探险，人们曾为它下过多次定义，有人认为它是勇敢者的游戏，也有人认为它是无谓的牺牲，可它的真谛和奥秘又有几个人清楚？ Exploration has been defined many times. Some people think it's the game of the brave and some think it's unnecessary sacrifice. But how many people know its essence and mystery? 探险的真谛或许只有真正尝试过的人才会明白，才会了解，也或许亲身经历过也无从得知。比如他们：走遍名山大川的李时珍，游遍祖国的徐霞客；七下西洋的郑和；发现新大陆的哥伦布；环球航行的麦哲伦；考察中国的马可·波罗……他们或许对“探险”的了解比我们深得多，可仍不会知道它的真谛。 The true meaning of exploration may only be understood by those who have really tried, or they may not know from their own experience. For example, they are Li Shizhen, Xu Xiake, who has traveled all over the famous mountains and rivers, Zheng He, who has traveled to the West seven times, Columbus, Magellan, who has discovered the new world, Marco Polo, who has visited China They may know more about "exploration" than we do, but they still don't know its true meaning. |
